MULTIPANEL Waterproof Balcony System 

MULTIPANEL manufactures a revolutionary, high-density, polyurethane composite building panel, ideal for waterproofing balconies as it is the first panel of its kind in the market that is truly 100% waterproof. 


NO MEMBRANE REQUIRED 
100% Waterproof

Many other panels are water resistant and hence rely on the need of a liquid membrane to waterproof a project. With MULTIPANEL, you have peace of mind knowing that the panel is immune to water and will act as a complete water barrier in all wet area situations.

Super Lightweight

MULTIPANEL is up to 80% lighter than traditional products. 30mm MULTIPANEL weighs only 18Kg per sheet (6.25Kg/m2)

Labour Saving

All edges of the panel are tongue and grooved for installation convenience. As MULTIPANEL is so lightweight and can be used without a liquid membrane, MULTIPANEL can be installed up to 75% faster than alternative balcony systems.

Eco Friendly

MULTIPANEL has been independently verified by EcoSpecifier as an environmentally friendly material. MULTIPANEL offers significant insulation advantages which offer increased savings for the total life of the project. There is also no material wastage as off cuts can be joined together using MULTIPANEL Polyurethane adhesive with joins becoming stronger than the panel itself. MULTIPANEL can also be joined off a floor joist, helping to minimise wastage.

Where is it used?

As an external substrate for tiled residential balconies and decks. It’s an alternative to particle board, plywood or compressed fibre cement. 



Waterproofing accounts for less than 2% of construction costs, yet industry groups and many building experts attribute more than 83% of building defects due to moisture related problems.
